MBIX now has its two route servers up and running on IPv4. We are still tweaking (as usual), but the route servers are operational. The service address for RS1 is 188.8.131.52, and RS2 is 184.108.40.206. They are implemented as BIRD running on Ubuntu, the hardware being used IBM 1U rackservers. We have two for redundancy, and also to allow orderly maintenance. Members peer with both route servers, allowing us to gracefully shut down one route server, while all routes are still announced by the other server, so MBIX stays 100% up.
Any savvy reader might be wondering about IPv6. Not to worry, we are testing that configuration now. MBIX intends to be fully dual-stack, (IPv4 and IPv6 simultaneously) but IPv4 was turned on first.
